Huh, I don't know how Alberta regulates insecticides. Here we had some pretty scary stuff coming over the border from the states, not sold up here, but also not regulated at the border by the feds. Province banned all pesticides somehow. Each one has to have some sort of safety testing done before it's sold here.
There's some weird legal wrangling that happened about what provinces have the right to regulate and what they don't, so they used what they could do to piss everybody off. Neem oil was on that list, as was a natural citronella mosquito repellent made in Quebec. It's crazy.
Anyway, I use the Safer's insecticidal soap on aphids. Works well enough, but can damage flowers. There's a rumour about it damaging trichomes, but I don't know if that has been confirmed.
